starts withThe maximum reported size is 19 mm (0.75 in). The exterior of the small shell of this species can have any one of a wide range of possible colors, from almost white, through yellow, pink, orange, red, purple, to brownish and blueish, with or without the presence of darker rays.
This species occurs on the east coast of the United States, from Cape May, New Jersey to Florida including East Florida, West Florida and the Florida Keys.
This species lives from the intertidal zone of sandy beaches to a depth of 11 m (36 ft). As most mollusks, the coquina is host to a variety of parasites. On the Atlantic Coast of the United States, studies have shown that coquinas harbour the larval stages (cercariae, sporocysts) of at least three species of digeneans (none of these represents a danger for humans).
